This class implements accessibility support for the JComboBox class. It provides an implementation of the Java Accessibility API appropriate to Combo Box user-interface elements.

Warning: Serialized objects of this class will not be compatible with future Swing releases.

    • getAccessibleChildrenCount

      public int getAccessibleChildrenCount()
      Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.
      Overrides:
      getAccessibleChildrenCount in class JComponent.AccessibleJComponent
      Returns:
      the number of accessible children in the object.

    • getAccessibleChild

      public Accessible getAccessibleChild(int i)
      Returns the nth Accessible child of the object. The child at index zero represents the popup. If the combo box is editable, the child at index one represents the editor.
      Overrides:
      getAccessibleChild in class JComponent.AccessibleJComponent
      Parameters:
      i - zero-based index of child
      Returns:
      the nth Accessible child of the object

      Overrides:
      getAccessibleStateSet in class JComponent.AccessibleJComponent
      Returns:
      an instance of AccessibleStateSet containing the current state set of the object
